BINDING STRAP.

Application filed May 5, 1921.

To all whom it may concern:

Be it known that I, Seaman Bnnonn, a resident of New York city, county and State of New York, and a citizen of the United States of America, have invented certain new and useful Improvements in Binding Straps, of which the following is a specification.

This invention relates to improvements in binding straps for securing coverings to pipes or to other elements. My strap is not limited to any particular use and of course can be used for any purpose for which binding straps are employed. One of the objects of my invention is to provide a binding strap having an eye or loop integral therewith. One of the objects in providing such a strap is to obviate the necessity of employing the usual rings or loops, which are applied to the straps at one end and which are apt to pull out. My improved strap consists of a strip of pliable metal having integral therewith and at one end, a loop or eye which is formed by suitable tools out of the material of the strip, said eye or loop being preferably of a greater width than the strip itself in order that the end opposite to the end carrying the loop or eye can be assed therethrough and bent over upon itse f to prevent slipping of the strap after it has been applied for binding purposes.

I will now describe my invention in detail, the novel features of which I will pointout in the appended claim, reference being had to the accompanying drawing, wherein:

Fig. l is a fragmentary perspective view, illustrating one of the uses for my improved binding strap;

Fig. 2 is a fragmentary view, illustrating the end of the strap which carries the eye or loop as it will appear after having been punched out;

Fig. 3 is a'similar view, illustrating the punched out portion of the strap as having received its initial forming operation;

Fig. 4: is a view, similar to Fig. 3, illustrating the eye or loop as formed in circular shape;

Serial No. 467,062.

Fig. 7 is a fragmentary view illustrating a completed eye or loop.

My improved binding strap consists of a strip 7 of any suitable relatively thin pliable metal adapted to be passed around any element to be secured in place, for instance around a covering 8 for a pipe 9, as illustrated in Fig. 1. To secure the covering, as well as to bind the strap, one end of the strip 7 will carry an eye or loop 10 through which the end 11 thereof is passed and bent over upon itself to form a bight 12 which is engaged by the eye or loop 10, as illustrated in Fig. 1.

To carry out my invention, I form the eye or loop 10 out of the material of the strip 7 by suitable tools. By this means I am able to provide a substantial anchorage for the free end of the strap, that is to say, an eye or loop that will not pull out or away from the remainder of the strap, and for this reason the eye or loop 10 excels in utility and durability the usual attached ring which is commonly made out of wire and attached to the strip. Furthermore, my method of forming an eye or loop produces a comparatively inexpensive binding strap.

To produce the eye or loop 10, I first punch out one end of the strip 7, as indicated at 13, Fig. 2, to provide an openingla and a partly circular ring 15 which is, of course fiat, and attached to the strip 7 by a neck 16. At the point where ring 15 and strip 7 are joined, I form recesses 17, one at each side of the strip, in order to facilitate the turning up of the peripheral edge 18 of the ring 15. After the strip has been punched out, the ring 15 will be, by suitable tools, formed into a circular channel, indicated by 19, in Figs. 3 and 5; In other words, the peripheral edge 18 and inner edge 20 will be turned up. After the ring has been thus partly formed into an eye, it will be again subjected to the action of suitable tools, which will act to turn edges 18 and 20 toward each other to form a ring having a substantially cylindrical cross section, as indicated in Figs. 4 and 6. The ring thus formed will now be flattened, as indicated in Fig. 7, to produce the eye or loop 10. The flattening of the ring 21 (Fig. 4) will increase its width, so that the completed eye or loop 10 will be wider than the strip 7, as indicated in Fig. 7. To fiatten ring 21, pressure will be applied in the direction of the arrow 22, Fig. 4:. By making the eye 10 wider than strip 7, it is possible to slip the hand through the eye in order to anchor the band by bending it 10 over upon itself.
